Description and Introduction

VERY LOW DROP 1.5 A REGULATORS The L4940V5 is a low-drop voltage regulator manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Output Voltage:** 5V  
- **Output Current:** Up to 1.5A  
- **Dropout Voltage:** Typically 0.5V at full load  
- **Input Voltage Range:** Up to 28V  
- **Line Regulation:** 10mV (typical)  
- **Load Regulation:** 15mV (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, TO-220FP, D²PAK  

### **Descriptions and Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Reverse Polarity Protection:** Protects the device if input polarity is reversed.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

The L4940V5 is commonly used in automotive, industrial, and consumer electronics applications requiring stable 5V power supply regulation.
